Why is PVC a renewable source?

I hope this helps x
PVC plays a major role in delivering and sustaining the quality, comfort and safety of modern life-styles. Its impressive ratio of cost to performance also means that people of all income groups can enjoy these benefits. High living standards are not just about the present, however. Future generations also have the right to material and other benefits. This is the foundation of the concept of ‘Sustainable Development’. PVC products are already helping every day to improve people’s lives and conserve natural resources in a world that is growing in population, with ever-increasing demands for water, food, shelter, sanitation, energy, health services and economic security.

It's cheap, durable, and efficient to make. It's not biodegradable as much, though, because it would take forever to disintegrate in a landfill.
